gas gauge

I recently had to change my fuel pump and when i put everything back together my gauge is dead needle points towards the bottom of the cluster… actually points right to cruise… anyone have any ideas suggestions???
thanks

ground wire…or one of the wires on the sending unit…the ground wire breaks really really easily … happened to me about a month ago

FSU wires for sure iv head to re-build 4 FSUs now

Ya, I’ve got a similar problem. My gas guage isn’t accurate and my temp guage sticks on the bottom. any thoughts??
